Array substrate, display device and manufacturing method

Abstract

The embodiment of the invention discloses an array substrate, a display device and a manufacturing method, and relates to the technical field of display devices. A second area of a transparent oxide active layer is used for forming a first electrode plate of a storage capacitor, so that the aperture ratio of the array substrate is increased. The array substrate comprises the oxide active layer and a pixel electrode, wherein the oxide active layer comprises patterns of first and second areas of the oxide active layer; the pixel electrode and the corresponding part of the second area of the oxide active layer form the storage capacitor; the second area of the oxide active layer forms the first electrode plate of the storage capacitor; the pixel electrode opposite to the second area of the oxide active layer forms a second electrode plate of the storage capacitor; and a film layer between the first and second electrode plates form a dielectric substance of the storage capacitor.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to an array substrate, a display device and a manufacturing method. Background technique [0002] In recent years, with the continuous advancement and improvement of the level of science and technology, display technology has developed rapidly. Based on its advantages such as high-quality image display, self-illumination, fast response speed, and wide viewing angle, OLED (Organic Light-Emitting Diode, organic light-emitting diode display) occupies a broad market in the display field, and more and more OLED Display devices are well known and widely used in daily life. [0003] However, the inventors have found that at least the following problems exist in the array substrate of the prior art: the storage capacitor in the OLED drive circuit in the prior art is formed by opaque metal electrodes and pixel electrodes, therefore, the opaque metal electrodes directly affec...
